According to the DNR, they are investigating a spill in a creek called “Orange City Slough Creek”.
They say the fish kill appears to have happened after a wrong switch was pulled Saturday evening at the Brian Roorda Dairy east of Maurice. The switch turned on a pump that moves manure from one lagoon to another. That caused the second lagoon to overflow. Manure from the lagoon ran down a grassed waterway into the creek.
The spill was discovered and then reported to the DNR on Sunday morning. The dairy was able to construct an earthen dam to stop the flow of the manure after the overflow was discovered.
Approximately five miles of the stream had been affected by the spill by early Sunday evening.
